Intelligent cement-based composite material with high pressure-sensitive sensitivity

Abstract

The invention discloses an intelligent cement-based composite material with high pressure-sensitive sensitivity. The intelligent cement-based composite material with high pressure-sensitive sensitivity comprises cement, silica fume, electrostatic self-assembly carbon nanotubes / titanium oxides, water reducing agents, sand and water. Compared with the prior art, the intelligent cement-based composite material with high pressure-sensitive sensitivity effectively solves the problem of dispersion of nano-scale fillers in cement-based materials, and the carbon nanotubes and micron-level titanium oxide assemblies are low in water absorptivity, so that the intelligent cement-based composite material with high pressure-sensitive sensitivity and small dosage of the electrostatic self-assembly carbonnanotubes / titanium oxides has stable and high pressure sensitivity on the basis of keeping a mechanical property.
